Ok, from left to right we have the Scosche LHA20, Axxess (Metra) XSVI-1731-NAV, and the Metra 70-1731/Axxess ASWC-1 combo.
First, none are perfect. The LHA20’s CANBUS decoder gives you parking brake, reverse, and illumination leads so you won’t have to find those under the dash or in the kick panel as well as a switched 12v output. However, it does NOT have a speed pulse wire or reverse camera input wiring of any kind (odd since it has a reverse lead). if you already have a 70-1731, you can use the camera input harness with the LHA20. Though, for the $90 the things costs, it really should come with it. It also does steering wheel controls.
The XSVI-1731-NAV has speed sense, reverse, and parking brake, but no illumination. It also has a rearview camera input, complete with the AX-CAM6V needed to send the 6V power the OEM camera needs. It does also have the wires in the correct location for the CAN-BUS wiring so the SWC should work fine. There’s also a spare 10-pin connector that is not mentioned anywhere in the “manual.” Oddly, it doesn’t come with the 3.5mm to single wire adapter needed for Kenwood and some JVC radios. Very weird.
Finally, the 70-1731/ASWC-1 combo. If you have the tools to depin the Metra harness, you can move a couple of wires to the right spot and make the SWC work with literally nothing but these parts. You will however have to source illumination, parking brake, reverse, and speed sense wires to tap into. Reverse and illumination have been documented here, but I have not seen a good spot for speed sense.
I’m going to try both the Scosche and the XSVI as I’m all for not having to source any more wires than I need to but the wireless CarPlay function REQUIRES a speed pulse wire and the Scosche doesn’t have it and I don’t have a schematic to find where it is in the car. The Scosche is the best IDEA, but the lack of reverse camera and input and speed sense wire is kind of silly. BUT, if you’re running a unit with an aftermarket camera (or have the camera harness from the 1731) and don’t need a speed sense wire, it feels the most well thought out and I love that everything is CANBUS controlled. If I can find the speed sense wire in the car, I may keep it, but right now I’m leaning to the XSVI
